Abstract
The growing demand for finding alternative applications for ceramic products wastes develops their usage as construction materials. The main objective of this paper is to evaluate the feasibility of recycled toilet bowl (RTB) wastes as pozzolanic materials in mortar mixture. The properties of RTB material were examined in terms of chemical composition, particle size distribution (PSD), X-ray diffraction (XRD) analysis, compressive strength, pozzolanic reactivity, sulfate resistance, and alkali-silica reaction according to ASTM C 618 and C 311 test specifications. The results demonstrated that the use of RTB materials as pozzolanic materials positively affects compressive strength development and durability by fully corresponding to all criteria of the ASTM C 618 guideline. Furthermore, chemical composition, PSD, and XRD test results had equivalent values to ASTM class F fly ash analysis.
